OnePlus 13s vs Pixel 9a: A Story of Two Phones

Updated on 16-Jun-2025

In an industry obsessed with binaries, flagship killer vs budget king, performance vs battery, and iOS vs Android, we often forget that some choices aren’t about being right. They’re about being you.

That’s exactly what the OnePlus 13s and Pixel 9a remind us. On the surface, they sit in the same pricing bracket, serve the same demographic, and promise the same thing: a “flagship-like” experience without blowing Rs 60,000. But peel back the packaging, and you’ll realise they approach the idea of a smartphone very differently. This isn’t just a spec shootout. It’s a reflection of user personalities and perhaps even philosophies.

The Philosophy of Phones: What Do You Want to Feel?

If the OnePlus 13s is biryani, layered, spicy, and a bit indulgent, then the Pixel 9a is dal chawal. Simple, comforting, and deeply satisfying in its own right. The metaphor sounds silly until you’ve spent a week switching between the two. One throws animations and brightness, and rapid-fire charging at you. The other quietly refines everything you already do.

OnePlus 13s flaunts a flagship-grade AMOLED panel, a beefy 5,850 mAh battery, and a Snapdragon 8s Gen 3 chipset that feels like overkill for casual users. Pixel 9a counters with balance: a new design language, a no-fuss user experience, and Google’s AI features that are less about fireworks and more about invisible convenience. That’s where the real divergence lies.

Design: Same Same But Different

Let’s start with what you touch. Both phones hover around the same weight: 185g vs 186g, but the way they carry that weight is completely different. Objectively, the OnePlus 13s is thinner, lighter, and arguably sleeker. Subjectively, it feels like OnePlus finally remembered how to design a phone that doesn’t just look good but feels effortless. The flat edges don’t bite into your palm. The Velvet Glass back is premium without being a fingerprint trap. It’s the kind of phone you forget you’re holding until someone asks about it.

Pixel 9a, in contrast, is chunkier and more confident. The new camera bar is gone, replaced with a subtle pill-shaped bump that makes the A-series feel like its own identity, not a hand-me-down flagship. The playful colourways like Iris and Peony don’t scream “serious tech”, and that’s kind of the point. It’s designed without pretence.

For those who care about symmetry, texture, and that slippery slope between elegance and ergonomics, the OnePlus 13s wins. But if you’re into quirk, personality, and honest charm, Pixel 9a speaks your language.

Display: Numbers Don’t Tell the Whole Story, But They Try

When you’re spending north of ₹40K, you expect a great screen. Both phones deliver. But again, they do it differently.

The Pixel 9a surprises immediately with its raw peak brightness: 2,700 nits on paper, nearly 3,000 in real-world testing. On a summer afternoon in Delhi, it holds up without squinting. HDR content looks fantastic. Maps in sunlight? Completely visible.

Colour accuracy is near studio grade. The average Delta E of 0.9 means the Pixel displays what’s real, true skin tones, neutral whites, and balanced contrast. You feel it when editing a Reel or viewing photos from a wedding shoot. What you see is what you get.

Now, the OnePlus 13s doesn’t try to match the Pixel’s brightness. It maxes out at 1,700 nits in testing. But instead, it leans into colour vibrancy. Delta E of 1.3 isn’t textbook accurate, but it’s pleasing. Reds are punchy, blues pop, and everything has this subtle cinematic saturation. The screen just feels alive, especially when you’re bingeing or gaming.

And then there are thoughtful extras: glove mode, wet-touch responsiveness, and a flat panel with uniform bezels that look far more premium than its price.

If outdoor visibility and true colour matter, Pixel wins. If you like drama in your visuals, without sacrificing quality, OnePlus holds its own.

Performance: Power vs Polish

Performance is where the lines get drawn in ink. Let’s not sugarcoat this: OnePlus 13s is a performance beast. Snapdragon 8s Gen 3. 12GB LPDDR5X RAM. 120FPS BGMI. Geekbench multi-core over 8800. AnTuTu has nearly 2.5 million. This isn’t a phone, it’s a heat-dissipating rocket ship. The 3D vapour chamber and extra graphite layer keep it cool even under stress. Gaming, editing, multitasking—it dares you to throw more at it.

In contrast, the Pixel 9a’s Tensor G4 posts pedestrian numbers. Half the scores, often a third in GPU metrics. It heats up quicker in extended gaming, and it doesn’t offer performance sliders or game modes. And yet, day-to-day?

Pixel 9a is smooth. Polished. Predictable in the best way. Apps launch fast. Switching is fluid. Multitasking works. It feels like someone went through your average day and optimised it from the inside out.

Because here’s the twist: Tensor isn’t built to flex muscles. It’s built for thoughtful assistance.

Where OnePlus opens Genshin at 90FPS, Pixel edits the background out of your kid’s school photo in one tap. Where OnePlus optimises RAM allocation for faster animations, Pixel suggests responses in context before you even think of them.

If performance is your end goal, OnePlus wins, no debate. But if performance is a means to a seamless, human experience, Pixel quietly outsmarts it.

AI & Software: This Is Where It Gets Personal

This is the first year where it really feels like AI is a feature, not just a buzzword. And both phones are surprisingly capable.

The Pixel 9a has the obvious edge: Magic Editor, Best Take, Real Tone, Circle to Search, Add Me, Pixel Studio, Voice Typing, Summarise, Live Translate… the list is insane. And the best part? They’re baked into the OS. No hunting for apps, no add-ons. Everything is just there, and it works.

But the OnePlus 13s doesn’t go down without a fight. Its new Mind Space + Gemini integration combo is genuinely clever. Want to search for a note from last week? Just describe it in natural language. Want live translation in a WhatsApp call? Done. Want AI to explain a document you’re reading on-screen? Sure.
And most of this works offline, thanks to on-device processing.

Pixel’s AI feels more invisible, like it’s helping you without asking. OnePlus’s AI feels more hands-on, like it’s giving you power tools for a digital world. But it’s clear: while OnePlus is integrating AI, Pixel is AI.

Cameras: Storyteller vs Showoff

This is the most subjective section, but also the most telling. The OnePlus 13s takes great shots. Sharp, colour-rich, instant post-worthy photos. Portraits are crisp. Night mode is usable. Close-ups are its secret weapon—detailed textures and well-balanced exposure.

But no ultrawide, and that hurts.

The Pixel 9a is thoughtful. It doesn’t try to dazzle. It captures moments with mood. Night Sight is still best-in-class. The dynamic range is better. Skies don’t get blown out. Shadows aren’t lost. And with AI edits, even a mediocre photo becomes a masterpiece.

Selfies? Pixel’s HDR is better. OnePlus occasionally overexposed.

Ultrawide? Pixel wins by default. It has one.

If you like natural, emotional storytelling in your photos, Pixel is your camera phone. If you like contrasty, vibrant, punchy shots and can live without ultrawide, OnePlus is still very satisfying.

Battery Life: More Than Just mAh

The OnePlus 13s laughs in the face of battery anxiety. On paper, the 5,850 mAh battery in the OnePlus 13s blows the Pixel out of the water. It delivers 21+ hours in PCMark testing, handles gaming, content, and doomscrolling with ease, and then charges to 100% in under 50 minutes with the 80W SuperVOOC charger.

Also, pass-through charging when gaming = a massive win.

Pixel 9a’s 5,100 mAh battery is no slouch. It lasts easily through a day, often more. The efficiency is real. But charging? 23W wired, 100+ minutes to full. It does support wireless charging, which is nice, but if you’re coming from a fast-charging phone, it’ll feel… sluggish.

If battery life and charging speed matter more than wireless niceties, OnePlus destroys this round.

So, Which One’s Better?

At the end of the day, the OnePlus 13s and Pixel 9a aren’t battling for supremacy. They’re asking different questions.

The OnePlus 13s asks, “What more can we give you at this price?”

The Pixel 9a asks, “What can we take off your plate?”

So if you want raw power, fast charging, cinematic visuals, and future-proof hardware in a compact package, the OnePlus 13s is a phenomenal deal.

But if you want stability, subtlety, thoughtful intelligence, and a phone that just feels like home, then Pixel 9a still holds its quiet ground. Both phones are compelling. Both are polished. And both reflect two very different ideas of what a phone should be in 2025.

This time, you’re not choosing specs. You’re choosing temperament.
